SynonymsDurio conicus Becc.

DescriptionUpper canopy tree up to 49 m tall and 85 cm dbh. Stipules present, but
falling off early. Leaves alternate, simple, penni-veined, silvery-golden below,
very similar to those of Durio acutifolius, but veins looping more
clearly and more conspicuous scales on lower surface. Flowers ca. 33 mm in
diameter, white-reddish, with 2-lobed epicalyx, placed in small clusters on the
twigs behind the leaves. Fruits ca. 160 mm in diameter, reddish, capsule with
long spines, seeds surrounded by dark yellow-reddish, edible aril.

EcologyIn undisturbed mixed dipterocarp forests (rarely peat swamp) up to 300 m
altitude. Usually on hillsides and ridges with sandy soils, sometimes on
limestone. In secondary forests usually present as a pre-disturbance remnant
tree, or planted for the fruits.
